Swarm not working

Hi all,
This is driving me crazy and I have spent hours on this and cant figure out why this doesn’t work. I have a total of 3 machines. A,B,C.

A is my main machine that I am running UE on and doing my builds on. B and C are my agents. I have them setup correctly, they ping each other and show up in the Coordinator window. See attch jpgs

The issue is the IP address for machine A is not 127.0.0.1 thats what shows up in the coordinator window. When I go to build I only get machine A to show up.

Why is the ip address not showing as I have set it up? How do I change the ip to show up correctly in the Coordinator window?

Any help would be appreciated.

Thx

Alex
